STRAW-STACKER AND CHAFF-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 689,793, dated December 24, 1901 Application filed June 5, 1901. Serial No. 63,258. (No model.)

to for a threshing-machine, the same being adapted to separate chaff from the straw and deposit them in separate stacks or piles.

The invention is embodied in the construc- 'tion, arrangement, and combination of parts 15 hereinafter described, and illustrated in the appended drawings, inwhich- Figure 1 is a vertical longitudinal section of the rear portion of a threshing-machine provided with our improved attachment. Fig.

2c 2 is a vertical transverse section on the lin 2 2 of Fig. 1. V Our invention is shown applied to a wellknown form of threshing-machine provided with a grain-winnowing attachment of the 25 usual construction and arrangement.

In Fig. 1, A indicates the fan of the strawstacker, B the fan of the chaff-stacker, and O and D the independent straw and chaff chutes, respectively. The chutes are con- 30 nected with the housings or drums E and F of the respective fans A and B and are in practice adapted to be raised and lowered and shifted laterally, as in the case of strawchutes with which many forms of straw- 3 5 stackers are provided. There being nothing new in the construction and arrangement of the chutes, detailed description is unnecessary. The chafi is delivered to the fan B by means of the flattened tube or chute G. The 0 upper side of said chute is formed by a transverse partition H, which extends upward and is attached to the grain-board I, arranged in the usual way beneath the reciprocating straw-racks J. The end oi-Iv the threshing- 5 machine is closed by the hood K, by which chute L is formed forconveying straw tcr the fan A. It will be observed that the fan A may be larger than the chaff-fanB and that the latter may bearranged under the former go or in any other convenient relative position,

the only requisite being that the chaff pas sage or tube G may be connected conveniently therewith. Both fans are preferably driven by same shaft M, although separate means may be provided for this purpose. The said shaft M is shown in a vertical, and the fans in a horizontal, position; but it is obviously practicable to arrange them at an angle, and we do not restrict ourselves in this regard. The said shaft M is provided with a beveled gear N, which meshes with a similar gear 0, keyed upon a transverse or horizontal shaftP. (SeeFig.2.) ThesaidshaftPisprovidedwith a belt-pulley Q and serves as the driving-shaft. A side belt (not shown) is arranged in practice to run on the said pulley Q. Thus both fans may be driven together and at the same speed and deliver straw and chaff to the respect-ive chutes O and B, by which they are deposited in separate stacks.

While the fans A and B are shown connected to same shaftand driven at same speed, it is obviously practicable to arrange them disconnected and drive them at dilferent speeds, and we do not restrict ourselves in this regard.

What we claim is- 1. The combination with a threshing-ma-' chine of the straw-drum and passage leading thereto, a chaff-drum and passage leading thereto, fans located in the respective drums, and the latter being arranged one under the other, and independent straw and chaff chutes connected with the respective d ru ms,as shown and described, whereby straw and chaflf are separated from each other within the threshfans, whereby they may be operated, substantially as shown and described.

3. An attachment for a threshing-machine, comprising two housings or drums, one below prevented from passing to the straw-fan and I0 is delivered to the chaif-fan, substantially as shown and described.
